    Yeh, I'll have to do that ... then I could join the AMD Users team - NOT

    Re: AMD Threadripper

    Do you want to add AMD Epyc 7000 series CPU discussion here or move to a new thread?

    AMD's info here...http://www.amd.com/en/products/epyc-7000-series

    Here's a wiki page...https://en.wikipedia.org/wiki/Epyc

    Hi-lites include...

    Single or dual CPU config

    16c/32t, 24c/48/t and 32c/64t CPU models

    Base freq from 2.0-2.4 Ghz

    All core boost from 2.55-2.9Ghz

    8 memory channels per CPU

    128 PCIe lanes per CPU

    Re: AMD Threadripper

    After looking at the cost/CPU I don't think we need a new thread $4700 per CPU (64t/CPU).

    Yeah, anything bigger than "enthusiast" level CPUs with 16C/32T still seems like crazy money...the corporations that buy the bigger stuff must have pretty deep pockets.

    I just saw an article that pitted the AMD Threadripper 1950X against Intel's latest i9 7960X (I think it was, whichever one has same core/thread count) anyway, after all was said and done, and they O/Ced both to 4.0GHz, here was the verdict:

    Intel CPU 16C/32T is ~30% faster, at same clock speed. However, it cost almost exactly twice as much. So...hard to say what's better if you have the money, I guess. But if price is a factor, that extra 30% is pretty expensive.

    Yep. Price/performance Threadripper easily wins. With Threadripper you also get 20 additional PCIe lanes, even if you only got the 8c/16t version.

    Re: AMD Threadripper

    Any avx 512 boric apps yet? If/when they start showing up, it will be interesting to get some real world performance comparisons.

    Rakesearch has an opti app for AVX 512 but I don't think anyone has showed up to use it yet. The Threadripper needs a special opti because it is slow executing some of the AVX2 instructions.
